Title: Device for compounding and/or processing thermoplastic, elastomeric or viscous compositions
Inventor: SCHUMANN KLAUS DIPL ING
IPC: B29C48/47
Filed: 1986-08-18
Abstract: The device can be used in conjunction with downstream units for various operations in the thermoplastic and elastomer processing industry. The aim of the invention is to improve the mode of operation of a device with disc-groove rotors and the versatile applicability of said device. The object of the invention is to design the device such that, with a high pressure build up, a forcibly conveyed, defined amount of material can be discharged per rotor revolution and, by virtue of a controllable connection of the annular channels, the process can be influenced directly. This object is achieved according to the invention in that at least one of the annular channels formed by the disc-groove pair is partly or completely closed against the material conveying direction by a disc with a recess and a closure element arranged in the groove of the other rotor and the material is thereby dammed up, with high pressure build up, and conveyed forcibly. The annular channels can be optionally connected to one another in the conveying direction by means of controllable overflow channels to influence the process. <IMAGE>

Filed: 1987-11-10
Abstract: The invention relates to a method and an arrangement for transferring plate-shaped workpieces, in particular printed circuit boards equipped with components, from one workpiece carrier to a second one. Printed circuit boards equipped with components, which are located in an equipping receptacle, are to be transferred, in a manner as free as possible from vibration and by the shortest route, into a workpiece carrier for the purpose of soldering the components on. At the same time, the method provides that the two workpiece carriers (17, 19) are positioned in a positionally correct manner one above the other in a transfer station, the clamping elements of the lower workpiece carrier (19) which holds the plate-shaped workpiece (22) previously being opened. By means of pressure, the gripping elements (10) of the second workpiece carrier (17) are opened and the workpiece carrier is lowered. The gripping elements (16) opened in this manner are moved through perforations in the lower workpiece carrier (19) and embrace the plate-shaped workpiece (22). The plate-shaped workpieces (22) are supported from above by advancing resiliently mounted struts (13). By means of pressure direction reversal, the gripping elements (16) are closed and, in a lifting movement, the plate-shaped workpiece (22) is lifted off the lower workpiece carrier. <IMAGE>

Filed: 1988-01-14
Abstract: An electric razor has a shaving head (10) and a hand trimmer and/or long-hair cutter (50), on the upper end of which there is mounted a trimmer block (60). The trimmer handle (50) has the shape of a flat plate which is displaceably mounted on a flat surface (23) on the outside wall of a razor casing (20), in order to permit vertical movement between a rest position and a plurality of operating positions. In the inside surface of the trimmer handle plate (50) there is formed a flat recess (52) in which there is arranged a trimmer drive (65) which connects the trimmer block (60) and a main drive element (30) for the shaving head (10) to one another in order to drive the trimmer block (60) and the shaver head (10) using a common source. The trimmer block (60) contains a stationary blade (61) and a movable blade (62) which between them determine a cutting plane which is parallel to the plane of the trimmer handle (50) in order to reduce the dimensions of the trimmer block (60) in the direction of the depth of the trimmer handle (50). The fact that the flat recess (52) is sufficiently deep to accommodate the entire trimmer drive (65) helps to make it possible to bring about a substantial reduction in the overall thickness of the hand trimmer (50) together with the trimmer block (60), so that the hand trimmer (50) only brings about an insignificant increase in the thickness of the entire razor. This means that the razor can be given a flat shape, making it easy to handle and to transport, and via ... Original abstract incomplete. <IMAGE>

Title: Method for the energy-saving heating of buildings and installation for carrying out the method
Inventor: WOLKE ERHARD
IPC: F24F5/00
Filed: 1988-01-18
Abstract: Known heating methods in which heated air is employed have either the disadvantage of a very high air temperature which results in an impairment of one's health or the disadvantage that a costly heat pump is required. These advantages are to be overcome by the invention. In the new method, air is heated underneath an absorbent roof skin, behind an absorbent facade cladding, in a gap between two window wings and in an exhaust-air heat exchanger and is supplied either immediately into rooms to be heated or to a long-term thermal-energy accumulator. As a result, the solar energy striking a building is optimally utilized and the operating costs are very low. The new method is suitable especially for use in suitably equipped relatively small dwelling houses, but also for office buildings, school buildings and like structures. <IMAGE>
